(Effect)
Four playing cards of the same number - "Four of a kind" - are shown to be riveted together in a RED-RED-BLACK-BLACK Order.
Due to the fact that they are fastened as such, it is impossible to change the order of the cards. The cards are handed to a spectator who is requested to close the fan.
When the spectator opens the fan, two of the cards have swapped place - altering the order to RED-BLACK-RED-BLACK.
The spectator requests to see the miracle one more time.
The spectator closes and open the fan, the fan is now returned to original order, RED-RED-BLACK-BLACK.
The cards remain in their own hands to be examined...
